HKS Turbo Kit Installation and Dyno Tune for Toyota 86/Subaru BRZ – 240kW Street Setup

HKS Turbo Kit Install and Tune

Our workshop recently completed a full HKS turbo kit installation on a Toyota 86, transforming it from naturally aspirated to a responsive and reliable boosted street car.

We began by fitting the turbo manifold and dual resonated front pipe. This upgrade is almost essential for turbocharged applications as it helps free up exhaust flow, allowing the engine and turbo to breathe better and make more power. The dump pipe was heat wrapped to manage under-bonnet temperatures before installing the turbocharger assembly.

Next, the compact but highly efficient HKS intercooler was installed. We carefully aligned all HKS logos and clamps for a clean and professional finish. Supporting upgrades included high-flow fuel injectors, flex fuel capability, and HKS Racing Super Fire spark plugs to ensure consistent performance and reliability.

For boosted 86 builds, we strongly recommend the HKS oil cooler. This turbo-specific version includes ducting and vents behind the wheel guard to keep oil temperatures in check during spirited driving and track use.

Results

Once the installation was complete, the Toyota 86 went on our dyno for a custom tune. The result was 240kW at the wheels on a safe street tune. While the HKS turbo kit is capable of more power, this level is ideal for stock engine internals and the factory gearbox. It provides strong, usable performance while maintaining daily drivability and reliability.
